protein that plays a role in supplying oxygen to mitochondria during exercise. They demonstrated that the myoglobin concentration in skeletal muscles is directly related to testosterone. Therefore‚ an increase in testosterone will allow for more muscular potential. In addition‚ Rogozkin (1979) conducted a similar investigation to identify the effects of anabolic steroids on protein synthesis in skeletal muscles. He discovered that they increase the number of fast-twitch muscle fibers and enhance

2011 Types of Tissue A tissue is a group of cells that have a similar shape and function. Different type of tissues can be found in different organs. In humans‚ there re four basic types of tissue: epithelial tissue‚ connective tissue‚ muscular tissue‚ and nervous tissue. There may be various sub-tissues within each of the primary tissues. Epithelial tissue covers the body surface and forms the lining for most internal cavities. The major function of epithelial tissue includes protection

endurance and motor performance tests were excluded. The influence of continuous and categorical moderator variables was assessed by meta-regression and subgroup analyses. The results of their analysis indicate that there is an ability to gain muscular strength in children and adolescents‚ and there is a noticeable boost during puberty. Reynolds is successful in conveying her idea that weight training is actually good for children and adolescents. She

2009 Available online 31 October 2009 Keywords: Aging Force–velocity Muscles Strength Power a b s t r a c t Aging in humans is associated with a loss in neuromuscular function and performance. This is related‚ in part‚ to the reduction in muscular strength and power caused by a loss of skeletal muscle mass (sarcopenia) and changes in muscle architecture. Due to these changes‚ the force–velocity (f–v) relationship of human muscles alters with age. This change has functional implications such

Neuromuscular blocking drugs were first used by South American Indians on their arrows to paralyze their prey. During that time neuromuscular drugs were called curare. They were first written about in a letter by a chronicler‚ employed by the Court of King Ferdinand and Queen Isabella‚ in 1516. In the 18th century Edward Bancroft‚ a physician‚ brought samples of curare back from South America and Sir Benjamin Brodie showed how small animals could be left alive after being injected with curare and

BENEFITS OF SWIMMING Introduction Swimming is an activity that burns lots of calories‚ is easy on the joints‚ supports your weight‚ builds muscular strength and endurance‚ improves cardiovascular fitness‚ cools you off and refreshes you in summer‚ and one that you can do safely into old age. By the 20th century‚ swimming had become mainstream. Indoor pools were beginning to appear‚ most towns with populations over 20‚000 had public outdoor pools‚ and swimming clubs became increasingly popular

cerebral cortex‚ lies at the base of the brain. Cerebellum primarily regulates posture‚ muscle tone‚ and muscular coordination. The cerebellum also stores memories related to skill and habits. Without the cerebellum‚ tasks like walking‚ running‚ or playing catch become impossible. The first symptoms of a crippling disease called spinocerebellas degeneration are tremor‚ dizziness‚ and muscular weakness. Eventually victims have difficulty merely standing‚ walking‚ and feeding themselves. Damage to
